What structure is this?

Background: Prep with black against London-ish players.

Question: At the end, or maybe one move or few moves before that, what pawn structure are we talking about?

Reason: I have the book "Chess Structures: A Grandmaster Guide" by Mauricio Flores Rio, but didn't recognize this structure.

I don't think this specific structure is one of the 'textbook' structures, but it looks like some kind of reversed caro slav to me.

Maybe minority attack may be in plan for black if white goes c3 to defend pawn

Reversed Catalan.

The Catalan looks like this:

From a dynamics point of view, I might see a reversed Caro-Slav structure: this would mean white ought to try to break with c4 or e4, and then use the semi-open d-file to its advantage.

White of course wants to prevent that and rather grabs the center space with ...e5 after trading with ...cxd4 first. Hopefully for black it could create a wedge in blacks camp with latter trade.

Am I on the right track here? (going by move 6. At the end the cxd trade happened and now only the space-grab remains for black.)

Edit: I totally forgot krikorian12 recognized the same structure. Duh. But hilarious too

This is a grunfeld set up....Im not sure if you can call it a grunfeld structure since white hasnt played c4 but I dont think that changes what black wants to do...basically put pressure on whites center with c5 and e5 pawn break but I would wait on c5.. In that first diagram....instead of 6..c5 I would play Nh5 giving black the option to get the bishop pair with 8. Be5 8..f6 9. Bg3. and maybe then go with the e5 plan c6 Nbd7 Re8 and maybe even Qc7 after exchanging on g3.

jamesstack I agree with you too entirely. For black it's Grünfeld and well positioned - having potential - to move up with ...e5, but first ...c5.

As it comes to your idea, the acquirement of the bishop pair, I have considered it a few  times but didn't pursue it yet. There's a lot of factors to take into account.

That having said, whilst we agree on black, I also think the white's side should be considered a Caro-Slav with the kind of play I pointed out earlier. White's reason to play the Jobava-version of the London (i.e. Nc3 obstructing his crucial c-pawn break) is surely to enable itself for a quick attack, at the expense of said c-pawn break, having only the e-pawn break left. But from what I understand the latter is a typical London theme anyway.

I think it looks like the caro kann that Kamsky used to play. He'd fianchetto his kb in his version of a caro kann. But a Caro where white started a  panov but veered into other waters.

By the way, Kamsky would've been world champion had he not quit after the Karpov match.
